Note: If the all the reference internal ports (4 bits) are set to â1â, or FMH mode or FML mode is set, the input is pulled down. Power input. When PLL is operating, 5 V * 10% is applied. The voltage can be dropped to 2 V in the backup status (when the CKSTP command is being executed). If the voltage drops below 3.5 V when the CPU is operating, the CPU will stop to prevent malfunctions. 53 VDD . initialized and the clock corrected by program as required. When the voltage O+ 3.5 V is applied to this pin, the system reset signal will be supplied to the device, and the program will start from address O. Note: Set the rise time of the device supply voltage between 10-100 ms because of the power on reset operation. (See note 1) 54 GND 1 . Ground of the CPU and logic block For the connection of a 7.2MHz crystal oscillator. Adjust the oscillation frequency 55,56 XT, XT (7.2MHz), observing the LCD segment waveforms. The oscillator stops automatically when the CKSTP command is executed. 4-bit (P5- 1- P5-4) I/O port. This port can designate inputs and outputs for every bit: 57-60 P5-1 - P5-4 Ilo the designation is executed by the contents of the internal port called PORT-5 I/O CONTROL. (See notes 1-3) When the voltage rises to more than 3.5 V, the CPU will restart.

This status (Wait mode) can be detected by the Wait F/F bit, so the CPU should be

Note 1: When a reset signal (VDD = O+ 3.5V and INI = âLâ + âHâ) is input to the device, the I/O ports will be set to inputs, the
common pins of I/O ports and AD/DA converters will be set to inputs of I/O ports, the common pins of I/O ports and serial UO ports will be set to inputs of I/O ports, and the common pins of IF counter inputs and I/O ports will be set to IF counter inputs. Note 2: When the CKSTP command is executed, all outputs of the output ports and I/O ports will be set to âLâ. Note 3: When the device is reset, the contents of output ports and internal ports are uncertain, so the device should be initialized by program as required.
